' SAFETY-RAZOR.

specification of Lette-rs Patent.

Patented Sept. 26, 1916.

. Application led August 28, 1915. Serial No. 47,773.

To alli/.17mm it may concern Beit known that I, RUSSELL E. WAKELEY, acitizen of. the United States, residing at the city of St. Louis, Sta-teof- Missouri, have Vinvented certain new and us'eful Improvements inSafety-Razors, of which the following is a specification, referencebeing had to the accompanying drawing, forming a part thereof.

This invention relates to certain new and useful improvements in safetyrazors, the object of my present invention being to provide acomparatively simple and inexpensive razor especially of the kind statedhaving areciprocating blade, whereby the act of shaving is quickened andfacilitated.

With the above and other objects in view, my invention resides in theprovision of a razor having a reciprocatorily movable blade and incertain novel features of form, p

construction, arrangement, and combination of parts, all as willhereinafter be described and afterward pointed out in the claims.

In the accompanying drawing, which illustrates my invention in preferredform, Figure 1 lis an elevational view of Aa safety razor embodying myinvention; Fig. 2 is an enlarged fragmentary longitudinal sectional viewthrough the same; Fig. 3 is an enlarged elevational view of my newsafety razor with several of the parts thereof in assembling v position;Fig. 4 is 'a view taken approximately on the line 4 4, Fig.. 2; Fig. 5is a transverse sectional view taken through the handle of the razor onapproximately the line 5 5, Fig. 2, looking in the direction of thearrows; Fig. 6 is a plan' view of the razor-blade forming part of my newrazor; Fig. 7 is an inverted plan view of one of the razor-bladeguard-and-securing plates; Fig. 8 is a' sectional view through the lowerportion of the handle of the razor, showing in section the razor-bladereciprocating or actuating means; Fig. 9 is a View taken approximatelyon the line 9 9, Fig. 8; and Fig. 10 is a view taken approximately onthe line ic-lo, Fig. s.

teriorly therefrom, is a rotatable rod or shaft 2, a bushing or the like3 being preferably provided in handle 1 at the projecting end of shaft2, as seen in Fig. 2. Fixed upon shaft 2 at its projecting upper end isa small arm or tappet 4, handle 1 at its upper end .being providedpreferably integrallyT with'a pair of diverging or oppositely disposedobliquely outwardly presented arms 5 5 having perforated extensions 6 6.

7 indicates a suitable end or blade-securing plate, whichis preferably,as is usual, transversely convexed on its outer face. Fixed upon theplate 7 at its opposite or inner face is a pair of preferably square-headed threaded studs or bolts 8 '8 adapted, when the several parts areoperatively assembled, to project through handle-extensions 6 6 toreceive securing-nuts 9 9.

10 indicates a suitable guard.- and bladesecuring plate, which isprovided at its opposite lengthwise edges with dull or faceprotectingteeth 11. Transversely plate 10 is provided with suitable perforationsor openings 12 12 adapted to freely accommodate the studs 8 8, plate 10being further centrally and intermediate perforations 12 12 providedwith an enlarged opening or aperture, as at 13, to accommodate thepassage through plate 10 to operative bladeengaging position when theparts are being assembled, of arm or tappet 4.

Adapted tooperatively loosely or .movably t between plates 7 and'10, isa blade 14 approximately rectangular in shape in plan view, asillustrated in Fig. 6, bla-de 14 being sharpened to a cutting edge, asat vided with rectangular slots 1(3 16 to accommodate and it the squaredportions of studs 8 8, and centrally intermediate slots 1,6 16 blade 14is provided with an enlarged opening or aperture 17 within which tappet4 is adapted to fit and work when the parts are operatively assembled.Extending into the area of opening or aperture 17 is a pair ofdiametrically opposite teats 18 18, as clearly seen in Figs. 4, 5, and6; aperture 17, instead of having a regular outline or perimetercircular in form, may thus be described ashaving a wall somewhatirregular or non-circular in outline. With the teats 18 18 or theotherwise so-called irregular outline orv Wall of aperture 17 tappet 4is adapted t0 alternately engage, as shaft 2 is rotated, to reciprocateblade 14:. It will be noted that, while blade 14 is of somewhat greaterwidth than the width of outer or end-plate 7, it is of somewhat lesswidth than the width of inner or guard-plate 10 with its teeth 1,1,teeth 11 being adapted to protect the face from injury by the cuttingledges 15 of blade 14 when the razor is in service, as in the act ofshaving, as will be well understood.

Suitably fixed upon handle 1 at its other or lower end, and surroundingthe lower end of shaft 2, is a preferably cylinmcal housing or casing19. Projecting into housing 19 and loosely fitting in shaft 2 at itslower end, is a spring-winding button or the like 20, fixed upon theshaft of which within housing 19 is a ratchet-wheel 21. Loosely mountedupon shaft 2 within housing 19, is a gear-wheel 23 having preferably alwidened hub-portion 24. Arranged within housing 19 and surroundinghub-portion 24 of gear 23, is a spring-barrel or casing 25, providedwithin which is a suitable coil spring 26, one end of spring 26 beingfastened-to casing 23 and its 'other end to hubportion 24 of gear 23.Ratchet 21- and spring-casing 25 may be formed integrally or otherwisexedly connected one with the other.

Mounted in suitable bearings 27 in housing 19, is a small shaft 28, xedupon which to mesh with gear 23 is a pinion 29. Also fixed on shaft 28is a gear 30 adapted to mesh with a. gear 31 fixed on main shaft 2, gear31, in turn, meshing with a gear 32 mounted on a shaft 33 supported insuitable bearings 34 in housing 19.

In use or operation, the blade 14 with its securing and guard-plates 7and 10 are operatively mounted on handle 1 by means of studs 8 and nuts9, as will be clear, slots 16 permitting' movement of blade lll betweensaid plates. YVith blade 14 in such position,

tappet 4 nts in perforation 17 to engage with said projections- 18. Apin 36 being now pressed inwardly to engage shaft 2 to frictionallyprevent rotation of shaft 2, spring 26 is wound within its casing 25through rotation of its winding-member 20. On pin 36 being released, asin the act of shaving, shaft 2, through said train of gearing described,will be rotated, Iwhereupon blade 14;, through alternate engagement oftappet it with said projections 18, will be reciprocated relatively tohandle 1, the act of shaving being thereby quiokened and facilitated.

Pivoted upon the lower wall of housing 19 is a pair of oppositelydisposed springpressed dogs 22 adaptedv to engage with. the teeth ofratchet 21 to prevent reverse rotation of ratchet 21 and its connectedspringcasing 25 under the influence or tension of spring 26, and toprevent too rapid rotation of shaft 2 under the tension of spring 26, I

preferably provide in connection with gear a centrifugal governor 35 ofany standard or approved construction adapted to frictionally retardrotation of gear 32 and.

its connected gearing, as will be obvious.

I am aware that changes 1n the form, construction, arrangement, andcombinatwn of the several parts of my new razor may` be made andsubstituted for those herein shown and described Withou-t departing fromthe nature and principle of my invention.

Having thus described my invention,`

what I claim and desire to secure by Letters Patent is:

1. In a razor, a handle, an end-plate, studs on said end-plate connectedto said handle, a guard-plate on said studs between said end-plate andhandle, said guard-plate having an opening, a blade niovably mount edbetween said plates, said blade having slots for accommodating vsaidstuds, a central opening registering with the opening of saidguard-plate, and a pair of diamet rically opposite tea-ts projectinginto the area of its opening', a rotary shaft in said handle projectingat one end into said registering openings, an arm on said shaft ittingin the opening of said blade and adapted to alternately engage with saidteats on 4rotation of said shaft, and means for rotating said shaft andits' carried arm.

2. In a razor, a handle havingr a pair of diverging extensions, anend-plate, a guard-1 gether, and means for rotating said shaft and itscarried arm to reciprocate said blade. In testimony whereofI haveattached my name to this specication.
